Corporate guru Charan (The Game Changer) and Conaty, a 40-year HR leader at General Electric, reveal how successful companies stay on top by developing leaders at every level of operation. Heading the list is GE under the leadership of Jack Welch. Nicknamed "Neutron Jack" for his ruthless willingness to fire non-performers, Welch created a new culture at GE by transforming the criteria for executive performance so that management had to get to know their workers, which allowed them to choose future leaders to develop in a series of room-to-grow jobs. The authors offer suggestions for adopting Welch's methods for today's global environment, examining not only GE but also Novartis, Hindustan Unilever, and Proctor and Gamble to suggest that today's leaders need to manage multiple brands in one country, shepherd a single brand across the globe, and spend time working abroad. A liberal use of jargon ("He searches for discontinuities in the external landscape") will distance general readers, but business types will find this useful. (Nov.)
